Hi! I have a WiFi card AX210 from AliExpress. Marking:
Mini PCI-E Wi-Fi 6E Card
Model: MPE-AXE3000H
P/N: 219250102

When connecting to an access point using 802.11ac (service netif start) I get a
kernel panic:
panic: page fault
cpuid = 2
time = 1750195319
KDB: stack backtrace:

#13 0xffffffff8102469b at fast_syscall_common+0xf8
If I disable 802.11ac in sysctl or in the access point settings, leaving only
802.11n (5 GHz), the kernel panic does not occur.
Also, the kernel panic does not occur if the wrong ssid is specified in
wpa_supplicant.conf.
